    Abstract: A motor driving circuit and a motor component are provided. The motor driving circuit includes a bidirectional alternating current switch connected in series with a motor across two terminals of an external alternating current power supply, where the bidirectional alternating current switch is connected between a first node and a second node; a rectifying circuit; a magnetic sensor, configured to detect a magnetic field of a rotor and output a corresponding magnetic inductive signal; a first voltage drop circuit and a second voltage drop circuit connected in series between the first input terminal of the rectifying circuit and the first node, where there is a third node between the first voltage drop circuit and the second voltage drop circuit, and the first voltage drop circuit is connected between the first node and the third node; a switch circuit connected between the third node and a control terminal of the bidirectional alternating current switch, where the switch circuit includes a first terminal, a second terminal, a control terminal and a switch arranged between the first terminal and the second terminal; and a switch control circuit connected between the control terminal of the switch circuit and an output terminal of the magnetic sensor.

    Abstract: A stator core includes at least one bendable strip-shaped core. Each strip-shaped core is formed by stacking a plurality of laminations. Each lamination includes at least two yoke portions and at least two tooth portions. Every two adjacent yoke portions are connected to each other via a bendable portion and have two opposite end surfaces, one of the end surfaces having a groove and the other having a projecting rib. After the bendable portion is bent the projecting rib is engaged in the groove to form an interlock structure such that relative circumferential movement between the adjacent yoke portions is limited.

    Abstract translation: 定子芯包括至少一个可弯曲的带状芯。 每个条形芯通过堆叠多个叠片形成。 每个叠片包括至少两个磁轭部分和至少两个齿部分。 每两个相邻的轭部分经由可弯曲部分相互连接并具有两个相对的端面,其中一个端面具有一个凹槽,另一个具有突出肋。 在可弯曲部分弯曲之后,突出肋接合在凹槽中以形成联锁结构,使得相邻磁轭部分之间的相对周向运动受到限制。
